This invention relates to machines'for making records on statistical cards.

In makin records on statistical cards, as for example, by punching holes therein, systems have been employed according to which a card of standard size is virtually divided into two halves longitudinally, the upper and lower halves of the card each having an equal number of half columns for the reception of records. This arrangement doubles the capacity of a standard card but requires that some form of coding be employed when making the records, for example a code according to which a single hole in onep'osition in a half column represents one digit, while a hole in the same position together with a second hole in another position in the same half column represents a diiferent digit.

The present invention has for its main object to provide an improved form of mechanism for actuating the record-forming elements in a machine for making coded records in either or both halves of each column of a record card which is virtually divided into two halves longitudinally as described above.

A further object of the invention is to provide a. machine Which can be used to make coded records in either the upper or lower half of a card, or to make single records each in a vfull column of a card.

'According to the present invention a machine for making records on statistical cards comprises in combination a column of record-forming elements whereof the elements in one half of the column of elements represent the same data as corresponding elements in the other half of the column, and in an embodiment of the invention now favored such machine comprises a plurality of crossbars each disposed with its ends resting on the upper ends respectively of two corresponding record-forming elements in the column, a pivoted'actuator for each crossbar, each of said actuators resting on its associated crossbar between the ends of the lattenand means for blocking downward movement of either end of each crossbar at will, whereby on depression of any actuator, the blocked end of the associated crossbar serves as a fulcrum about which said crossbar rocks to operate the record-forming element on which its other end rests, the other record-forming element remaining inoperative.

The record-forming elements may be in the form of punches for perforating record holes in the cards, and in this connection a presently preferred embodiment of the invention is a machine comprising in combination a column of punches whereof each punch in one'half of the column has the same value as 'thecorrespondingly positioned punch in the other half of the column, a plurality of double-armed levers each having one end resting "on the upper end of a punch in one half of the column and its other end resting on the upper end of the corresponding punch in the other half of the column, a pivoted actuator for each of said levers, each of said actuators resting on the associated lever midway between the ends of "the latter, and means for locking the punches in either half of the column against downward movement at will, whereby ondepression of any actuator the locked punch on which one end of the associated lever rests serves as'a fulcrum about which the associated lever rocks to operate the unlocked punch on which its other end rests.

According to a further feature of the invention each of the record-forming elements in the column may be provided with an additional pivoted actuator individual thereto and'overlying a projection or shoulder on the associated recordforming elements, and the machine may include means for disabling the blocking means for all the record-forming elements simultaneously, whereby the same machine can be used for recording data by single records (e. g., perforations) each in a full column of (e. g., twelve) index point positions, or by one, or two, records (e. g., perforations) duplicated in the lower and upper halves of a column of (e. g., six) index point positions, or by records of the latter kind in either half column. I

In order that the invention may be more fully understood one embodiment thereof will now be described by way of example with reference to the accompanying diagrammatic drawings which illustrate the invention applied to a machine for forming records by punching holes in statistical cards.

Fig. 13 is a detail view, showing in'top plan a ho izontal locking plate, together with certain associated devices. and i Fi 14 illustrates a mod fication of the means for blockin the punches allottedlto either half column of a record card and for then rendering operative the punches allotted to the other half column.

In the drawings like references indicate the same or similar parts.

In the embodiment illustrated in the drawings the machine comprises a'bedplate I carrying supports 2 across which'is secured, by screws 3, a lower bridge plate 5. Below the bridge plate 4 the bedplate I carries a die plate 5 having twelve holes 5a therein, and above the die plate a stripper plate 6 formed with twelve corresponding holes.

The lower bridge plate 4 is formed witha longitudinal opening 1 (Fig. 5) through which pass the punch carriers. These last are twelve plates 8 each havin a punch 9 de ending from its. lower end. Plates 8 are guided at their upper ends by a comb plate is secured to the lower bridge plate 4 by screws l l and a retaining bar 12 secured to the plate 4 by screws [3. At their lower ends the plates 8 are guided by the passage of the punches 9 through the respective holes in the stripper plate 6. A. spring [4 is disposed around each punch 9 between the stripper plate 6 and the lower edge of the corresponding plate- 8. said springs urging the punch upwardly, and the upward movement being limited by engagement of a shoulder 8a' (Fig. 7) on they plate 8 with the underside of plate 4.

Themachine thus includes twelve punches arranged in a column in accordance with the twelve recording the 0 and 9 values alongside each other.

, punches with values so assigned thereto that the The machine asdescribed herein is intended for use in punching sterling monetary amounts and the six index point positions in each half column are used to represent the even digits or values, 0, 2, 4, 6, 8, and the odd digit 9, while the 7 other odd digits are respectively represented, by the next higher even value position and the 9 position, the digit 11 being represented by'the 0 and 9 combination. 7

In other words, as shown in Fig. 10, each even number-0, 2, 4, 6, 8--is recorded by punching a single hole in the card, the odd number 9 is similarly recorded, and the other odd numbersl, 3, 5, '7 and 1l-are each recorded by punching two holes one of which is always the same T punching as for the 0 hole. The number or value and 9 combination is used for recording the num her 11, it is desirableto have the punches for Hence the machine herein illustrated includes six punches for the values 2, 4, 6, 8, 0 and 9 are arranged in that order relative to the index point this bunch, which in these two views is additionally marked A, isthe 2-value punch and the next five punches to the right. which in regular sequence are additionally marked B, C, D, E and F (see also Fig. 11), are respectively for recording the values 4, 6, 8, 0, and 9. The six punches 7 shown in Figs. 3 and 7 beyond the punch Fare in these views additionally marked A, B, C, D,

E. and F; the punch A for recording the same value as the punch A,*the punch B for recording the same value as the. punch B, and so on.

It will be seen that in order to punch holes in the various index point positions only six punches are required for each half column, so that the 7 column of twelve punches may be regarded as being divided into two half columns of six punches each, and each punch in one half column as having a punch'of corresponding value in the other even digits 2, 4, 6, 8, '0, whilefthe sixth (indicated at a) is appropriated to the digit 9.

Each of the five actuating bars 2|! and the actuating bar 20a rests freely on a pivot pin 2| engaging in a socket 22 formed in the underside of the bar, said pin 2I projecting vertically from a holder 32 pivotally mounted at the centre of a corresponding crossbar or double armed lever 23. Each crossbar 23 has one end 24 resting on the upper end of a plate 8 in one half column and its other end 25 resting on the upper end of the corresponding plate 8 in the other half column.

Considering for example the plate 8 carrying the 2-value punch in the left hand .half column in Fig. 3, which is the punch additionally marked A in this view, and the corresponding plate 8 carrying the 2-value punch in the right hand half column, which is the punch additionally marked A in this view, then a crossbar 23 common'to these two plates will have its ends 24 and 25 resting respectively on the left hand plate and the right hand plate, the common crossbar 23 being'operable by the one actuating bar 20. Such crossbar is the one shown to the left in Fig. 7.

The pin 2| through which a bar 29 or 20a transmits movement to a cross bar 23 is mounted as follows:

As can be seen from Fig. 6 the crossbars 23 are mounted side by side in contact and are held in position by two stepped plates 39 and 3| of which the steps engage the ends of the bars 23 to maintain them in correct position. Plate 39 is supported on short posts I 6 to which it is attached by screws I! and plate 3| is supported on short posts I8 to which it is attached by screws I9. Each pin 2| is carried by a holder 32 rounded at the bottom to fit a correspondingly rounded depression 33 formed in the upper edge of the -crossbar 23 so that the bar 23 can rock about the centre of the lower end of the member 32.

It will be seen that four of the members 32 are held in position laterally by the adjacent crossbars 23 and in order to prevent the two outside members 32 at the right hand end and left hand end in Fig. 6 from falling out. a retaining plate 34 is screwed to the outside face of each of the two outside crossbars of the group.

As can be 'seenfrom'Fig. "7 the plates 8 are cut away at the to as indicated, for example at 8b in Fig. '7, to admit the downwardly projecting portion 231; of any crossbar which passes over them, this downwardly projecting portion being provided to strengthen the cross bar in view of the depression 33 formed in the upper edge of the bar 23 to receive the member'32.

The position of the pivot provided by the pin 2| and the socket 22 in each actuating bar 25 and in the actuating bar 23a is near the left hand end of the actuating bar in Fig. l. and close- 1y adjacent to its left hand end the actuating bar is freely pivoted about a fulcrum pin 35- screwed into an upper bridge plate 31. The fulcrum pin 35 is rounded at its lower end and enters a socket 36 in the upper edge of the bar.

Accordingly by depressing the right hand end of a bar 20 or 20a in Fig. 1 the-bar rocks clockwise about the fulcrum pin 35 and through pivotal connection 2|, 22 will move the associated cross bar 23 bodily downwards.

In order to effect this rocking of the crossbars 23 each of the five bars 20 (corresponding to the digits 2, 4, 6, 8 and 0, respectively) is provided with a key lever 38 (Figs. 2 and l2)'1oosely pivoted on a shaft 39 (Figs. 1 and 2) mounted in bearings 40 projecting upwardly from the upper bridge 31, each key lever 38 having a key stem 4| provided with a key 42 for operating it. Each key lever '38 also has a downward nose 43 (Figs. -1 and '7) formed on its under edgewhich bears on the upper edge of the actuating bar 2|) therebelow near its right hand end so that depression of a key 42 rocks its key lever 38 down about the shaft 39 and thereby actuates said bar by rocking it down about the pivot 35, 36.

The key 42a bearing the numeral 9 is similarly connected to a key lever 38a freely mounted onthe shaft 39 and carrying a pin I50 (Figs. 2 and 12) overlying the 9 actuating bar 20a. Thus depression of the No. 9 key will actuate the bar 20a, but rocking of the shaft 39 will not affect the No. 9' key.

Each of the five keys 42b bearing the numerals "3, "5, "7, and "11 is similarly connected to a key lever 38b freely pivoted about the shaft 39 and carries a pin I5I. Each of these pins overlies a step I52 in one of five collars I53 (Figs. 2 and 7) fixed to the shaft 39. Each key lever 3812' also carries a pin I54 overlyingthe actuating bar 26 which is directly actuated by the key 42 bearing the next higher even number, i. e., the key lever 38b of the "1 key 42b carries a pin I54 overlying the bar 20 for operating the 2-value punclnand so on. I The lever 38b of the "11 key 421), however, carries a pin I54 overlying the bar 20 for operating the O-value punch. v

Secured to the shaft 39 is an arm I55 carrying a pin I56 overlying the bar 2041 for operating the 9-value punch.

When any key 42b is depressed the pin I54 on its key lever 38b rocks the actuating bar 20 corresponding to the next higher even number and the pin -I5I on said lever acts through the associated collar I53 to rock the shaft 3'9 and at the same time the arm I55 through the pin I56 rocks the actuating bar 20a. Thus depression, for example, of the 5" key will rock the actuating bar 20 for operating the 6-value punch and also the actuating bar 2 Ila for operating the 9-value punch.

Each lever 38b carries a depending lug 38c and these lugs together with a similar lug I550 act as guides for the ends of the bars 20, 20a.

The mechanism as so far described is similar to that described in British patent specification No. 434,499, except for the crossbars 23 and an added tier or bank of punches.

The upper bridge plate 31 is supported (Figs. '1 and 3) by four posts 44, one at each corner, standing up from the supports 2.

From the foregoing it will be observed that with the construction thus far described actuation of any key 42 will through its lever 38 force down the actuating bar 20 underlying such lever and thereby cause depression of both ends 24 and 25 of the associated cross bar 23 simultaneously, with the result that the two plates 8 engaged by the two ends of said crossbar will both be depressed so that the apparatus would tend to punch a hole in one half column of the card and also a hole of the same value in the other half of the same column. A similar result is obtained by actuation of the "9 key 42a as then the pin I50 on the lever 38a, which pin overlies the actuating bar 20a, forces this bar down thereby to depress both ends of the cross-bar engaged by the bar 20a. Also, when any of the keys 42b is actuated, these for punching a two-hole record, the appropriate one of the actuating bars 20, and with it the actuating bar 20a, will both be rocked down, and each'of these two downrocked bars will act on the associated'two cross bars simultaneously; and the consequent depression of both ends of these cross-' bars will operate the four plates 8 engaged by said ends, so that the apparatus would tend to .7 and 8) are provided, one on each side of the column of punches 9. The slides 59 and are 7 guided in slots formed in a bracket 52 secured to the inside face of the left hand support 2 and at their right hand ends (Figs. 3 and 8) in slots formed in aplate 53 secured to the inside face of the right handsupport 2. The right hand end of each slide passes through an opening 54 (Fig.

3) in the support 2 and is cut away underneath to leave an 'overhanginglug- 55, the lug 55 of the slide 58 carryinga pin 56 and the lug 55 of the slide 5| carrying a pin 56a, for actuating the slide in the manner described below. Each slide also carrie'sa 'pin 51 guiding a spring 58 and passing through a plate 59 screwed-to the outside of the right hand support -2 which is cut away at 69; Fig. 8, for the purpose described below. The springs 58 are compressed between the end of the slide and the inside of the plate 59.

The slide 59 has six teeth 6| on its upper edge for co-operation with the plates 8 carrying the six punches 9 in the left hand half of the column (Fig. 3) and the slide 5| has six teeth 62 for co-operation with the six plates 9 carrying the punches in the right hand half of the column,

see Fig. 7.

The spacing of theteeth 6| on slide 50 and'of the teeth 62 on slide 5| is the same as the pitch of the punches 9 and by displacing the slides longitudinallyv each slide can occupy a left hand, or effective position, or a right hand, or ineffective position.

The slides are provided with an interlock as hereinbelow described, by means of which when one slide is set in the effective position the other slide is set in'the ineffective position and vice versa. and if for example the slide 50 is moved to the right hand end of'its travel (Figs. 3 and 7) to position its teeth between the punches 9 of the left hand half column, at the same time the slide 5| is moved to the left to position its teeth 62 below the plates 8 carrying the punches-9 in the right hand half column to lock these punches against downward movement, leaving the punches in the other half of the column free to be oper-' at'ed so that each of the locked punches serves as a, fulcrum about which the corresponding crossbar 23 rocks to depress the corresponding-punch in the other'half of the column.

With the slides 59 and 5| in the positions shown in the drawings, if for example the 2 key 42 is depressed this key will cause the actuator bar 29 at the extreme left in Figs.- 3 and 7 to rock clockwise thereby moving the corresponding crossbar 23 downwardly. Sincethe right hand end of this bar is resting on the 2 plate 8 in the right hand half column which carries the punch 9 additionally marked A and since this plate is locked against downward movement by the corresponding tooth 62 of the slide 5|. this plate 8 will serve as a fulcrum for the right hand end 25 of bar 23 which will consequently rock counterclockwise about this end, and its left hand end 24 will depress the plate 8 in the left hand half column which carries the punch 9 additionally marked A, thereby perforating a card with a hole in the ,2 value position in the left hand half column. 7 V

Conversely if the slide 59 is moved to' the left thereby locking the plates 8 in the left hand half column and the slide =5| is at the same time shifted to the right depression of the 2 key 42 key will cause the corresponding crossbar 23,

to rock clockwise about the plate 8 in the left hand half column thereby depressing thecorre-- spending-plate in the right hand half column to punch a hole in the 2- value position in that half column of the card.

In order to control the slides 59'and 5| the following mechanism is providedi Pivoted about a pin 64 extending across the opening 69 (Fig. 8) in the support 2. are two levers 96 and 61 (Figs. 2, 3, and '7), the lower end. of. lever 86 abutting against the pin 56 of slide 50, while the lower end of lever 61 abuts against the pin 56a on the right hand end of slide 5 The upper ends of the levers 66 and 6'! project into a slot marked 98 in Fig. 2 cut in the right hand end of the upper bridge plate 31 and engaging the upper end of lever '66 is a lug 89bent down from a setting slide 18 while the upper end oflever 61 is engaged by a corresponding lug 1| bent down from a setting slide 12. At their right hand ends in Fig. 3, the slides 1'0 and 12 are guided by a bracket13 (Figs. -1 and 2) screwed to a top plate I4 secured to the upper bridge plate 31 byscrews 15 and at their left hand ends the slides are guided (Fig. 9) in slots formed in lugslfi, I6 bent up from the top plate 14.

The setting slide HI-is controlled by a key 89 (Figs. 1, 2 and 9) attached to a key 'steinBl passing through a slot 92 in a plate 83 supported by four posts 84 extending upwardly. from the upper bridge plate 3|.- The lower end of the key stem 8| (Fig. 9) is cut away to form acam face 85, the reduced end 86 of the stem passing through a slot 8! in the plate 14, this slot also extending through the plate 81 beneath. As the slot 81 must be the full width of the key stem 8| to allow for depression of the latter a guide. 88 is provided which bears against the rear face of the key stem. This guide 88 is constituted by a lug bent off from a strip 89 secured at 99.

V to a post 9| upstanding from the plate 14.

In order to controlthe setting slide 12 a key 92 having a key stem 93 is provided, the keystem 93 being cut away at its lower end to form a cam face 94 and being guided in the same manner as key'stemsl. I r V The key stems BI and 93 are urged upwardly by means of springs 8 la and 9341 respectively, the

last-mentioned spring not being seen in Fig. 9

but being shown in Fig. 1.' v v 'On depression of, for example,,the key 80 the cam face 85., acting on a shoulder 95 of the 'setting slide 19 pushes said slide rearwardly (to the left side in Fig.8) into its ineffective position against'the action of a spring 95, the slidere- V maining locked in this position by a latch 91 pivlower end of said lever acting on' the pin 56 pulls oted at 98 to the post 9| and acted upon by a spring 99. In Fig. 9 the latchr9'l is shown spaced away from the post 9| for the sake of clarity, whereas. in fact the latch is close up against the post as-can be seen from Fig. 1.

. When the control slide 19 moves in the. abov described manner'the lug E9 rocksthe lever 66 counter-clockwise about the pivot 64 and. the

the slide 58 tothe right into the position shown in Fig. 7 against the action of'spring 58, thereby upper half column so that the punches in the upper half column are free to operate.

If it is now desired to punch holes in the. lower half column of a card the key 92 is depressed and the cam face 94 acting on a shoulder I of the setting slide 12 pushes said slide rearwardly into its ineffective position against the action of a spring. IN, the slide remaining locked in this position by a latch I02 pivoted at I03 to the post 9I, and acted upon by a spring I94.

When the control slide 12 moves thus the lug 1| rocks the lever 61 counter-clockwise about the pivot 64 and the lower end of said lever acting on the pin 56a pulls the slide 5| to the right in Fig. 7 thereby bringing the teeth 62 in between the plates 8 in the lower half column so that the punches in this half column are now free to be operated.

In order to disable the punches in the upper half column when thekey 92 is depressed the key stem 93 carries an arm I05 having. a depending lug I06 disposed above the tail of the latch 91 for the slide I0 so that when key 92 is depressed the lug I06 rocks latch 91' to release the slide which is moved to the right in Fig. '7 by its spring 96 (Fig. 9) thereby'moving lug 69 away from the upper end of lever 66. Spring 58 (Figs. 3 and 7) then pushes slide 50- to the left thereby bringing its teeth GI under the plates 8 in the upper half column so that these plates serve as abutments about which the levers 23 rock to actuatethe punches 9 in the lower hali column.

Similarly the key stem 8| carries an arm I0-1 having a lug I08 depending above the tail of the latch I02 for the slide 12 so that on depression of the key 80 the lug rocks the latch I02 to release the slide 12 thereby permitting the spring 58a to push the slide 5I to the left and thusbring the teeth 62 under the plates 8 of the lower half column so that these plates-serve as abutments about which the cross bars 23 rock to actuate the punches 9 in the upper half column.

In orderto enable one and the same machine to be used for punching data either in a full col-- umn or in a lower orupper half column at will, each of the twelve punches 9 in the full column may be provided with an independent actuating lever IIO controlled from a corresponding one of a bank of twelve additional keys I I I I.'

Each of the actuating levers H0 (Figs. 1, 2,11 and 12) is connected. to the stem IE2 of its key III by a loop II3 formed at the end of the lever H0 and embracing a reduced portion I'M'of the key stem. See in this connection the key stem H2 at the right in Fig. 1, and the 1 key III in Fig. 11.

As illustrated in Fig. 1' and in the case of the 2" key 42 in Fig. 12, the just described manner I of coupling the key stems I'I2 with the levers I I0 is employed also for operatively connecting the keystems II of the keys 42 with the levers 38, the key stem of the key 42a with the lever 38a, and thekey stems of the keys 62b with the levers 381).

'Each lever H0 at its forward end has a depres-- sion 5 in its upper edge which is maintained in engagement with a pivotpin I-IG by a bracket I I1 screwed to a plate '8 depending from th edge of the lower bridge-plate 4.

Each key lever IIO ,overliesa pin H9 (Figs. 3, 9- and 11) projecting from the side of the plate 8 carrying the associated punch so that, assuming the punches to be free to move, depression of any of the additional keys II I willcause operation of the corresponding punch 9.

In order thus to free the punches; and so condition the machine for punching data in a full column a third control key I20 for the slides 10 and 12 is provided as shown best in Fig. 9. The stem i2! of this key is guided in a manner similar to that described for thekey stem BI and the lower end of this key stem I2I is cut away to form a cam face I22 wide enough to overlap shoulders I23 and I24 on both slides 19 and 12 simultaneously.

With the parts in the positions shown in Fig. '7 the slide'iil is in its rearward position so that the slide 5!) controlled thereby is in its ineffective. position to the right and the punches in the upper half column are free to operate, the punches in the. lower half column being locked by the teeth 32 of slide 52 which has been permitted to move to the, left by slide 12 which has been moved to the right by its spring .IOI.

On depression of key I20 the cam face I22, acting on shoulder I24, pushes slide 12 also rear wardly in which position it is held by latch I02. By this means slide 5i will have been moved to the right thereby releasing the punches inthe lower half column so that all the punches inthe complete column are. now free to be operated. by the additional bank of keys III.

If it is desired for example to revert to punching in the upper half column. only, then key 00 will be depressed whereby the lug I03 will release the latch I02 for the slide 12 thereby permitting slide SI to move to the left and bring its teeth 32 under the plates 8 in the lower half column and so looking them, leaving the other slides 10 and 50 in the position shown in Fig. '1 so that the punches in the upper half column are free to be operated.

It is desirable as a safeguard to lock the keys II I of the additional bank when the machine is set for punching in either the lower or the upper half column of a card, and to. thisendeach slide 10 and 12 carries an upstanding pin I25, I26 (Figs. 2, 3 and 7) co-operating with a lever I21 (Figs. 1, 2, and 13) pivoted at I20 to the underside of the keyboard plate I29. Mounted in grooves formed between the underside of plate I29 and the underhanging flanges I 300i bars I-3I is a locking plate I32 for the key stems I I2, this plate having slots I33, marginal cut-outs I33 and other marginal shapings as shown in Fig. 13, each for providing an edge portion engageable in a notch formed in an adjacent stem; one of such notches being marked -I IZa in Fig. 13. Onan extension I35 of the plate I32 is a pin I36 against which abuts the end I31 of lever I21.

When either key or 92 is depressed the respective pin I25 or I26- rocks the lever I21 counter-clockwise about its pivot I23 and the end. I31 of the lever pulls the locking plate I32 into a position in which its slots I33 engagethenotches of the key stems I I2 thereby locking them against operation.

When both slides 10 and 1:2 are in their rearward position owing to depression of key I20 the lever I21 is free and a retractile. spring I39 pulls the locking, plate I32 into a position in which its .slots I33 are. disengaged from the notches in the a bail-plate I09 (Figs. 1 and 8-) extends below the punch carrying plates 8 and carries'brackets I6I by means of which-it is pivoted, on pinsl62.

Freely mounted on a shaft IE3 is a bail I64 carrying near its centre alug I651which is engaged I by a tail I56 projecting from a small adjustable 7 plate Ififia '(Fig. 8) having two slots lfifib for screw securementto the bail plate I56. When any of the plates 8 is depressed its lower right hand corner, in Fig.- l rocks plate I6 counter-clockwise about its pivots I62 and the tail I66 rocks baillfi. V V

The bail ie l'co'rresponds to the horizontal 7 part of the angle plate I1 described in British patent specification No. 430,251, and carries a pin I 61 bearing on an arm' I68 by means of which the escapement 'pawl IE9 is operated. The parts I61, I68,-and I69 correspond to the parts 29c, 29

and 24 described in the British specification No.

430,251 above referredto.

Instead of employing the two locking slides 56 and El described above, the teeth 6| of the slide Elland the teeth 62 of the slide i, may be disposed on a single locking slide disposed along one 7 side of the column of punches 9. Sucha construction is illustrated in Fig. '14, where a single slide'l15 is shown as longitudinally shiftable on fixed parts I16,"I16 of the machine and as carrying along itstop a group of teeth I11, correspending to the teeth GI, and also a group of teeth I18, corresponding to the teeth 62.

The group of teeth I18 are displaced along theslide, from thegroup of teeth I11, by a distance equal to half the pitch of the punches 9, so that, when the slide isat one end of its travel, the teeth I11 will be disposedbelow the plates 8 in the one half column while the teeth I18 are in between the plates 8 of the other half column, whereas when the slide is moved to the other end of its travel the teeth I11 will bebetween the plates 8 in the one halfcolumn, and the teeth I18 will be below the plates 8 in the'other half column. The plates 8 and punches!) are indicated in Fig. 14 in dotdepress the corresponding punch in the other halffcolumn in th 7 above.

e manner already described The'single locking'slide maybe biassed to one a of its extreme positions by means of a spring I80, and a key I8I may be provided to displace it-to the otherposition, a latch device I82,releasable on actuation of another key I83, being provided to retain the slide in the position to which it has :been set by the first mentionedkey. The keys .I8I and I83 are shown as provided with conven- V tional return springs I84 and I85 respectively.

Normally the slide I15, connected as at I85 to one end of the spring I80,"and with the other end of this spring connected to a fixed part of the machine as at I81, would be positioned as shown' against a stop I88. On depression of the key I ill, the lower end of its stemwould act cammingly' relative to an inclined edge portion I89 on the 'slide, to shift the latter a sufiicient distance to the left to dispose the teeth I18 below the plates 8 'carrying'the 'sixipunches at one end of the column of punches 9 and to ,placethe teeth I 11 between the plates 8;carry.ins. the. other six punches; The 7 latch I82, which includes a tooth tee the slide and a dog I9! fixedly pivote'd at 192', would look the slide as thus s'hifted,ifollowing clockwise rooking of the dog by thelto'oth' I90 during movement of said tooth to'the' left, at the conclusion of which movement the spring I85 would cause the do to drop behind the tooth I98. With the parts so arranged, the slide I would be returned to V th position shown on depression of the key I33,

which would rock the dog counterclockwise and break the latch I32'to free the'spring I 80 for returnof the slide.

Constructions according to the invention in V which means is provided for unlocking all twelve 7 parts lengthwise, or for'punching data in the r punches in the column simultaneously or for locking the six punches in either half column at will have the advantagethat 'asingle machine can be used for punching standard (e. g.,; column) cards or for punching data in the upper half of-a standard card which is divided into two lower half of such a card.

Although the invention has been particularly 7 described with'reference to l5 column cards having twelve index point positions in each column it will be understood that it is also applicable to cards having a greater or smaller number of full 7 columnsand with any even number of index point positions in each full column or in that part of each full column on which the mechanism according to the invention is intended to operate;

Further although the formation ofrecords by punching has been particularly described by way of example, the record forming elements may be arranged to impress the records on the cards in other'ways, e; g., by printing spots, or making electro-conductive marks on the cards.
